The highest I've seen is the 2017 Babolat Pure Strike 16x19 (Project one7), at 91 (combined, overall playtester rating. That is, taking into account all the combined playtester scores). The 2017 Pure Strike 18x20 is close at 89. Several come in at 88, the 2016 Pure Aero, the Ezone DR 98, the Pure Control 95+, and a few others.
